The fast route to a deep single-storey rear extension in Bedhampton — up to 6 metres on an attached house or 8 on a detached one — via Havant Borough Council's prior approval scheme rather than a full planning application.
Havant Borough Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Bedhampton contains Brockhampton, Old Bedhampton, Old Bedhampton conservation areas (Brockhampton designated 2026), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Havant Borough Council needs a full application. Bedhampton carries at least one Article 4 direction, and conservation areas including Brockhampton, Old Bedhampton and Old Bedhampton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Bedhampton is determined against an 8-week statutory target.
Brockhampton (conservation area designated in 2026), Old Bedhampton (conservation area designated in 2026), Old Bedhampton (conservation area designated in 2026) and The Black Dog (conservation area designated in 2026) — these are the Bedhampton pockets our drawings cover most. Heritage designations here include Brockhampton, Old Bedhampton, Old Bedhampton and The Black Dog. Havant Borough Council weighs each proposal against Havant Borough Council's adopted local plan and its householder design guidance, where the 4,790 homes here are 43% 1955-1964, 14% 1945-1954, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and simple gabled and hipped roofs typical of early postwar building, over late-1950s and early-1960s houses (43% of 4,790 homes), early postwar houses (14%) and 1930s semi-detached and detached houses (7%).
Heritage designation is the single biggest variable in Bedhampton, and it is address-specific: Brockhampton (conservation area designated in 2026), Old Bedhampton (conservation area designated in 2026), Old Bedhampton (conservation area designated in 2026) and The Black Dog (conservation area designated in 2026). Inside those boundaries permitted development is curtailed and Havant Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Havant Borough Council has 6 recorded Article 4 directions — check the address before assuming PD applies in Bedhampton.
On stock, Bedhampton is late-1950s and early-1960s houses (43% of 4,790 homes), early postwar houses (14%) and 1930s semi-detached and detached houses (7%) — which is why shallow gabled roofs typical of that period's building and simple gabled and hipped roofs typical of early postwar building govern what a loft or rear projection can realistically be. Havant Borough Council decided 286 householder applications in the latest published year and granted 95%, with 31% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Bedhampton runs pre-1900 3% (140 homes), 1900-1918 2% (80 homes), 1919-1929 2% (100 homes), 1930-1939 7% (340 homes), 1945-1954 14% (670 homes), 1955-1964 43% (2,070 homes), 1965-1972 4% (190 homes), 1973-1982 1% (30 homes), 1983-1992 3% (140 homes), 1993-1999 1% (70 homes) and 2000-2008 3% (150 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Havant Borough Council also decides for Havant St Faith's and Hayling West, so a decision in Bedhampton sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.
The Article 4 directions recorded for this council include 0164B1, 0164B2, 0164B3 and 2967. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.
The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Brockhampton and Old Bedhampton cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.
Bedhampton is largely late-1950s and early-1960s houses (43% of 4,790 homes), early postwar houses (14%) and 1930s semi-detached and detached houses (7%). Bedhampton contains Brockhampton, Old Bedhampton, Old Bedhampton conservation areas (Brockhampton designated 2026), so materials, fenestration and roof form are assessed against the appraisal, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. Havant Borough Council has 6 recorded Article 4 directions — check the address before assuming PD applies in Bedhampton.
The scheme is available where all of these hold. Fail any one and it is a full application to Havant Borough Council instead:
We prepare the notification pack Havant Borough Council needs — plans, elevations, a site plan with the adjoining owners identified — and manage the 21-day neighbour consultation so the 42-day clock is not restarted by an incomplete submission.
Below is Havant Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Havant Borough Council granted 95% of its householder applications in the year to 31 March 2026, and Brockhampton shapes what is approved here. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Brockhampton, Old Bedhampton and Old Bedhampton, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.
The 4,790 homes here are 43% 1955-1964, 14% 1945-1954, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.
We prepare prior-approval notifications across Bedhampton. A few of the areas where deep rear extensions come up most often:

Same extension, two routes, very different tests.
| Route | Depth allowed | What the council may consider | Timescale |
|---|---|---|---|
| Ordinary Class A permitted development | 3m attached / 4m detached | Nothing — no application needed | Immediate |
| Larger home extension prior approval | 6m attached / 8m detached | Amenity of adjoining premises, only if a neighbour objects | 21-day consultation, 42-day determination |
| Full householder application | No fixed limit | Design, materials, policy, amenity, everything | 8-week target |
| Any of these on designated land | 3m / 4m only | Prior approval scheme unavailable | Full application beyond the limits |

A process built around the 21-day consultation, which is where these schemes are won or lost.
Send us your Bedhampton postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.
We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.
We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details Havant Borough Council needs to start the consultation.
We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.
Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify Havant Borough Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land. This applies to your Bedhampton address specifically.
It is a notification, not an application for permission. You tell Havant Borough Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope. This applies to your Bedhampton address specifically.
The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Bedhampton address specifically. Havant Borough Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Brockhampton and Old Bedhampton, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to Havant Borough Council.
Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Bedhampton address specifically. Havant Borough Council is the decision-maker.
Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Bedhampton address specifically. Havant Borough Council is the decision-maker.
We quote each Bedhampton scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day. It covers the notification pack and free revisions until Havant Borough Council determines it. Call 020 7864 7245 to start.
